OK for the third time. I considered the Nuvinci 360, but read it used the Autobike algorithm for shifting. Having had an Autobike I decided against the Nuvinci. Went instead with the Shimano DI2 Alfine 11 speed hub with a new front 40 tooth chain ring and crank arms. Different feel to it , but I kept my top end of 20 to 22 mph and picked up 3 lower gears for hills. Shifting is seamless going to a bigger gear, but it likes no pressure on the crank going to smaller gears. So far I am liking the change.... (only 200 miles on the new setup so far). Previous change was to a 20 tooth sprocket on the back to bring up the top en, BUT lost the lower gears for hills. Now I have 3 low gears for hills and electronic shifting. Pricy , but worth it to me.
